perspective view of one of the foraminous clamps; and Figs. 13, 14 and 15 are transverse sections of the inner mold with the foraminous clamps in different positions 5 showingthe relative movements of such clamps toward Ithe mold during the waterexpressing operation.

In the drawings, l is a bed-plate supported in any suitable maner as on legs 2.

3 is a gear wheel loosely mounted on a crank shaft l suitably mounted to revolve in. bearings 556 in the bed-plate, and having dian'ietrically opposed cranks 5, 5 to which are pivoted connecting rods 6, 6, the other ends of which are pivoted to carriages 20, adapted to be reciprocated above the bedplate hereinafter described.

The gear wheel 3 meshes with a pinion 7 mounted on a stub shaft 8 adapted to revolve in bearings in the plate l, and is connected to a spiral gear 9, andl which meshes with a worm gear l0 mounted on a-main driving shaft ll suitably supported in bearings l2, and having a pulley 13 mounted thereon at a suitable place, and which pulley is actir ated by a beltlnot shown) from a suitable source of energy.

Each reciprocating carriage 20 comprises a rectangular' casting adapted to reciprocate on slideways 1-il supported upon and -secured to thel bed-plate l. Each carriage :ias mounted rigidly on its inner end a plate l() on which are mounted holders 500 as hereinafter 'described Slidably mounted within the carriage 20 is a hollow shaft' 2st within which is a second shaft 23. The inner ends of the shafts 24 and 23 are respectively pivoted to forked levers (STO and G70a mounted on the plate llt The outer ends of the shafts and 24 are turned at 23 and 2l and formed into hooks which are adapted to engage cams l5 and l5 which are fast to a transverse shaft lo suitably mounted in bracket bearings 17 and connected to lhedriving shaft ll by bevel gears 18 `and lf). (")ver the eenter of the hed-plate l there is arranged a double track 32. rl`his is adapted to support a number of arbors i on each and of which are mounted male molds TO ulrich are conveyed along the l will surround or envelop the inner molds T0,

which in the particular' form shown are l'rusto-conlcal in` shai'le, and which have had :leiosited thereon (during the 'previous opmr-ration elthe amiaratus) a coating of fresh a e pl astic fgn'aterial C.

'outside of the casino'.

The holder 500 comprises lirst a casing 5l which is substantially octagonal in section at its inner end and which tapers toward the outer end, at which point it merges into a cylinder 52 and, as it continues, merges into a yet smaller cylinder 53 secured to the plate 40. Suspended within the casing 5l are two vertical squeezers 800 and two horizontal squeezers 800, each covering approximately a quarter of a eircleon its inner surface.

The tivo vertical squeeZers are pivoted at Sl through projecting lugs and are suspended from the casing 5l by pairs of toggle levers 5l, 54 pivoted at 5G' between lugs 55 on the Each set of toggles 54, 54 is connected by a cross bar (3l pivoted to them at 5T and 58. The vertical squeezers are further supported by guide pins 59 which project through the easing 51 and screw into the squeezers. Compression springs 60 are provided between the head. of each pin 59 and the casing and they tend to draw the squeezers away from the center of the mold. The horizontal squeezers 800 are similarly suspended by pivots Sll and toggle levers 54 pivoted at 56 between the lugs 55a on the outside of the easing 5l. Each set of toggles 54 is connected by a bar 61"' pivoted to the toggles 54 at 5T and 58a. v

Means are provided for operating the vertical squeezers 800.' Ai bar G2 is pi voted at one end to the toggles 54:, 54 at 58 and at the other end to a pin 63 mounted in lugs 6l made integral with a cylindrical collar 65 slidably mounted 0n the reduced portion 52I of the casing 5l. The collar 65 is provided with an annular flange G6 grooved to receive pins (S00 on the end of a forked lever-G70 pivoted at 68 to thc plate 40, the other end of which lever is pivoted to the hollow shaft 2l having the hook 24 adapted to engage the cam l5u (sce Fig. l); It is evident that when the hook ill engages the high portion ou the cam l5 the shaft 24 will be drawn out, thus rocking the lever (3G and pushing which is pivoted to the plate all), and the other end of which lever is pivoted to the rod 28, the hook Qr being adapted to engage I he cam .lo is tuned to ahead of the horizontal the cam l5. move slightly squeezers 800% The male mold 70 consists ofv a hollow cone having a cyliiulrical portion 7U at its smaller end and a cylindrical. portion 70 at messie its larger end. The portion is reduced to form the arbor 33 which may be'integral therewith or suitably secured thereto. It is adapted to be attached to a similar inner .mold on its opposite side.

The construction of the vertical and horizontal squeezersl 800 and 800a is as follows. The construction being the same, the' description, willfbe analogous. Referring to Figs. 6 andS, the squeezers 800 are substantially rectangular in shape. rl`heir inner surfaces conform to that of the innermold and are .approximately a quadrant in cross section. They are also provided with radial partitions 82, to form air passages 83 which terminate in a common chamber 84 at the small end of the. mold having an outlet pipe 85 adapted to be connected to iie'Xible pipes 86 leading to an 'exhaust air pump. A curved sieving plate 870 made of woven wire or similar foraminous material is attached to the inner surface of the squeezers. By the proper timing of thecams l5 and l5il which move the vertical and horizontal squeezers 800 and 8002, the vertical squeezers will move in synchronism and likewise the horizontal. squeezers, but thevertical squeezers will move slightly in advance of the horizontal squeezer. their progressive positions being shown in Figs. 13, 14 and l5.

lt will be understood that the conveyer is intermittently moved 'so that the inner molds are brought to rest opposite the squeezer .holders 500. The purpose of the apparatus is to cause the holders to envelop or surround the inner molds while they are at rest and to cause the squeezers to move toward and tightly embrace the material on the molds so as to express or squeeze out the excess water therein, and then to cause the squeezers to move away from the molds and, the holders on their carriages to be reciprocated out of the Way of the conveyor to allow the inner molds to continue on their journey. li: is obvious that the movement of the parts must be timed to perform their functions in proper succession. To that end ig mechanism is employed which `ie described. The gear wheel 3 is, as stated above, loosely mounted to rotate on the crank shaft 4. (in each side of it and fixed on. the shaft.v are collars 550 which serve to fix its position. 0n one side its hub is extended to form one member 551 of a clutclg, the periphery of which member is prov d with sloping teeth 552. Alongside of the gear 3 is a disk 5.53having a bevcled edge 554- and which disk is mounted. on the shaft 4. and rotates thereafter and is adapted to slide longitudinally thereon, he ing secured key indicated at 555. lts

A`hub is extended to form the second member ,i557 of the clutch above referred to, and its periphery is provided with sloping teeth 55.8 adapted to engage the teeth 552. A compression spring 559 tends to press the disk 553 toward the gear 3 and to promote the engagement of the clutch members. A. gear 560 mounted on a shaft 561 adapted to rotate in bearings in the frame of the shaft is in constant mesh with the gear 3. Also mounted on the same shaft 561 is a cam disk 562 having arranged at diametrically opposite places on its edge two inwardly projecting cam surfaces 563. This disk is so placed that these cams overlap the edge of the disk 553, so that as it rotates, twice in each revolution when the cam surfaces 563 contact with the disk 553, the latter is moved against the tension of the spring 55.)', its clutch member is moved out of engagement with the clutch member on the gear 3, and while so out of engagement 4the power of the main shaft l is not transmitted to the crank shaft 4, and the carriages are at rest, and this period of rest occurs at each end of the stroke due to the diametrieally opposite positions of the cam surfaces 553.

The operation of the machine is as follows; Supposing the parts are in the positions shown in Figs. 6 and S, the squeezers tightly clamped against the inner mold, the holders being at their innermost position. The shafts'23 and 24 will disengage from the cams l5 and 15a by the continued rotation of the latter. This will cause the levers 670 and 670a to move slightly and break the lock of the toggle levers 5e, 54a and the squeezers under the influence of the springs 60 are moved away from the inner molds which they have surrounded and coincident with that movement the levers 670 and @70a with the rings 66 and 55 take their original position, so that the parts are brought to the positions shown in Fig. 7. in the meantime the continued rotation ofthe gear 500 has brought the cam plate 562 into position to operate the clutch and transmit the power from the main shaft l1l through the crank shaft e tov cranks 5 and carriages 2O and the holders 50() will move avv/ay from the inner molds to the end of 'the stroke. rlhe carriages will then rest until the clutch is again operated,.when they will move toward the oonveyer until they reach the innermost position and again surround the inner molds. At the end of the stroke, the shafts 93 and engage the cams l5 and 15 and operate the toggle lever system and lock the squeezers down upon the material on the inner molds, moving the two vertical squcezers slightly in advance of the two horizontal squeezers. As the compression'of the plastic material occurs, a section is placed on the conduits 83 and tends to remove themoisture squeezed out of the material. The cycle of operations is then repeated.
